This movie was supossed to be a movie Stephen Spielberg could make. Well sorry boys, think again. If I was Spielberg I would have pulled my head off (glad I'm not him!). The movie is slow, unrealistic (its Ci-Fi...) I mean the things that happen raise a lot of questions of how do those stupid kids survive all that mess. Its a sorry combination of E.T., The Goonies and a couple of other movies and to be honest this one does then all wrong!
